BACKGROUND OF THE INVENTION

The present invention relates generally to snowboards and, particularly to a snowboard having front and rear protective mechanism.

Snowboards are used in snowboarding, which is a winter sport both for fun and improving health. Participants in this sport usually have a high speed and inertia. Therefore, front and rear ends of the snowboards can easily be deformed or broken as a result of being striked, thus decreasing useful lifetime of the snowboards. To address this problem, snowboards with rear and front protecting strips (usually made of nylon PA or PUP by injection molding) are developed. In these snowboards, however, the protecting strips are pre-manufactured and wrap around the front and rear ends of the snowboards using adhesive and screws. The manufacturing method can be complicated and the snowboards appearance can be poor. In addition, the protecting strips are thin and weak and thus does not have sufficient strength, and the connection of the protecting strips and the front and rear snowboard ends is poor, which make the protecting strips unable to withstand big striking. When subject to big striking, the strips can easily be deformed, broken, or even become separated from the snowboard, thus failing to protect the snowboard.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 through 4, the present invention provides a snowboard having front and rear protective mechanism. In accordance with an embodiment thereof, the snowboard includes a snowboard main body and a pair of shock resistant protecting plates 3 attached to front and rear ends of the main body.

The snowboard main body forms a front mounting slot and a rear mounting slot at the front and rear ends thereof, respectively. The snowboard main body includes, from bottom to top, a bottom plate 11, a lower fiber glass layer 12, a core plate 13, an upper fiber glass layer 14, and a panel 15, which are laminated together in that order. A cutout 130 is defined in each of the front and rear ends of each core plate 13. The cutout 130 has a shape such that outer edges of the front and rear ends matching with inner edges of their corresponding protecting plates 3. The front and rear ends of the core plate 13, the lower fiber glass layer 12, and the upper fiber glass layer 14, cooperatively form the mounting slots (not labeled) at the front and rear ends of the snowboard.

Referring to FIG. 2, the protecting plates 3 have a same configuration except that they are mounted in different positions. Each protecting plate 3 is made of a material with high structural strength and high resistance to shock, such as metal materials, for example, aluminum, iron, white iron, and the like, by means of, for example, die-casting, casting, stamping, or CNN machine shaping. Alternatively, the protecting plate 3 may be made of a material with high structural strength and high resistance to wear, such as plastic materials, for example, nylon, fibered nylon (i.e., nylon containing fiber), PC (Polycarbonate), and the like, by means of injection molding or CNC machine shaping of plastic plate. One of the protecting plates 3 is mounted in the front mounting slot with an outer portion thereof extending out of the front mounting slot, and the other of the protecting plates 3 is mounted in the rear mounting slot with an outer portion thereof extending out of the rear mounting slot.

Referring to FIG. 3, an underside of a part of the protecting plate 3 that extends out of the mounting slot protrudes so as to form a step 30 thereon. The step 30 is coplanar with a bottom surface of the snowboard main body. The front and rear ends of the bottom plate 11 respectively abut against inner sides of the steps 30, thus further increasing the shock resistant capability. Rubber films 4 are attached to top and bottom surfaces of a part of each protecting plate 3 that is received in each mounting slot.

The snowboard further includes side steel frames 16 disposed at two opposite sides of the bottom plate 11, rubber strips 17 disposed between the bottom plate 11 and the lower fiber glass layer 12, ABS (Acrylonitrile Butadiene Styrene) strips 18 disposed at two opposite sides of the core plate 15, and screws 191 fastening the bottom plate 11 with the core plate 13. Screw washers are attached around the screws 191. The screws and washers may be hexagonal head screws and hexagonal washers.

Before assembly, the protecting plates 3 are pretreated so as to form a layer of transparent high temperature resistant protecting film on a surface thereof. As to protecting plates 3 made of metal materials, it is necessary to apply a sandblast to the extending parts of the protecting plates 3 out of the mounting slots. Components of the snowboard main body are then assembled. Specifically, the lower fiber glass layer 12 and the core plate 13 are laminated on the bottom plate 11, the protecting plates 3 with attached rubber films 4 are disposed in the mounting slots at the front and rear ends of the core plate 13, afterwards, lamination of the upper fiber glass layer 14, the panel 15 and other assembly steps may be performed according to normal assembly procedure. A front portion of the assembled snowboard is illustrated in FIG. 4 in a top view.

On the parts extending out of the mounting slots, the protecting plates 3 can form various marks or notes 5, such as, for example, trademarks, company logos, individuation characters, thus providing the snowboard product with individuation, good appearance, and brand advertising effect.

Shock tests have been conducted with regard to the prior traditional snowboard without protective strips, the traditional snowboard with wrapped protective strips, and the present snowboard with front and rear protective mechanism, respectively. The test results are shown in the following table.

Shock test results Angle 45° 50° 55° 60° 65° Joule once twice once twice once twice once twice once twice Remarks Traditional 50.6 50.6 The last values are snowboard maximum values without measured at strips breakage of the Traditional 50.6 50.6 61.9 61.9 73.1 73.1 samples. snowboard with strips Present 50.6 50.6 61.9 61.9 73.1 73.1 88.1 88.1 snowboard

It can be seen from the table, the present snowboard has higher resistance to shock than the prior snowboards.
